Without working the problem, I say no. For one thing the units are incorrect.Butterfly30 said:a 1000 kg car is moving down a road with slope (grade) of 15% while slowing down at a rate of 3.7m/s^2 .What is the direction and magnitude of the frictional force?(define positive in the forward direction)
Using f=ma
I have the mass 1000 kg, the acceleration 3.7m/s^2, and slope 15%
Would my force be the tangent of the angle 15??

To calculate the frictional force, you can use the formula F = μmgcosθ, where μ is the coefficient of friction, m is the mass, g is the acceleration due to gravity, and θ is the angle of the grade.
Acceleration is an important factor in determining frictional force because it affects the normal force acting on an object. The greater the acceleration, the greater the normal force, which in turn increases the frictional force.
The grade or incline of a surface affects frictional force by changing the angle of the normal force acting on an object. As the grade increases, the normal force becomes more perpendicular to the surface, resulting in a greater frictional force.
Mass plays a role in determining frictional force because it affects the normal force acting on an object. The greater the mass, the greater the normal force, which in turn increases the frictional force.
The coefficient of friction is a measure of the roughness or smoothness of the surface an object is moving on. A higher coefficient of friction results in a greater frictional force, while a lower coefficient of friction results in a lower frictional force.
